Advice, urgent

Hello All.

I have the following problem.

There is a parts master file and each part have its own sublevels and each
of these sublevels could have its own sublevels.

For example.

     Part P1 has 3 levels
               a) logo
               b) Color
               c) Imprint

     Now i could have SubLevels for the option (b) like this
     Color has 3 levels
               b.1) Position
               b.2) Color Imprint
               b.3) Cut Size

     And also i could have Sublevels within this Sublevels.

What i am trying to store all the part levels with its sublevels into an
array like this

     Array Index          Value
     1         Logo
     2         Color
     3         Position
     4         Color Imprint
     5         Cut Size
     6         Imprint

And the reason for me to store into an array because lets say the user
wants to delete the color option from the part, I need to delete all the
sublevels with the color options including sublevels within sublevels.

Please advice how can i do this in RPG or RPGLE and remember each sublevels
could have its sublevels and so on.

Thanks Again.
